This document is for CakePHP's development version, which can be significantly different
from previous releases.
You may want to read
current stable release documentation instead.
The Inflector class takes a string and can manipulate it to handle word
variations such as pluralization or camelizing and is normally accessed
statically. Example:
Inflector::pluralize('example')
returns “examples”.
You can try out the inflections online at inflector.cakephp.org or sandbox.dereuromark.de.

Both pluralize
and singularize()
work on most English nouns. If you need
to support other languages, you can use Inflection Configuration to
customize the rules used:
// Apples
echo Inflector::pluralize('Apple');
Note
pluralize()
should not be used on a noun that is already in its plural form.
// Person
echo Inflector::singularize('People');
Note
singularize()
should not be used on a noun that is already in its singular form.
These methods are useful when creating class names, or property names:
// ApplePie
Inflector::camelize('Apple_pie')
// apple_pie
Inflector::underscore('ApplePie');
It should be noted that underscore will only convert camelCase formatted words. Words that contains spaces will be lower-cased, but will not contain an underscore.
This method is useful when converting underscored forms into “Title Case” forms for human readable values:
// Apple Pie
Inflector::humanize('apple_pie');
When generating code, or using CakePHP’s conventions you may need to inflect table names or class names:
// UserProfileSetting
Inflector::classify('user_profile_settings');
// user-profile-setting
Inflector::dasherize('UserProfileSetting');
// user_profile_settings
Inflector::tableize('UserProfileSetting');
Variable names are often useful when doing meta-programming tasks that involve generating code or doing work based on conventions:
// applePie
Inflector::variable('apple_pie');
CakePHP’s naming conventions can be really nice - you can name your database
table big_boxes
, your model BigBoxes
, your controller
BigBoxesController
, and everything just works together automatically. The
way CakePHP knows how to tie things together is by inflecting the words
between their singular and plural forms.
There are occasions (especially for our non-English speaking friends) where you may run into situations where CakePHP’s inflector (the class that pluralizes, singularizes, camelCases, and under_scores) might not work as you’d like. If CakePHP won’t recognize your Foci or Fish, you can tell CakePHP about your special cases.
Define new inflection and transliteration rules for Inflector to use. Often, this method is used in your config/bootstrap.php:
Inflector::rules('singular', ['/^(bil)er$/i' => '\1', '/^(inflec|contribu)tors$/i' => '\1ta']);
Inflector::rules('uninflected', ['singulars']);
Inflector::rules('irregular', ['phylum' => 'phyla']); // The key is singular form, value is plural form
The supplied rules will be merged into the respective inflection sets defined in
Cake/Utility/Inflector
, with the added rules taking precedence over the core
rules. You can use Inflector::reset()
to clear rules and restore the
original Inflector state.
